CIFS kernel panic #2480
In 1800.4.0 (and 1828.1.0), accessing a CIFS mount will cause a kernel panic. This was working properly in 1745.7.0. First noticed in stable and tried alpha channel, same problem persists. Fresh install of 1745 works properly.
Container Linux Version
Both 1800.4.0 and 1828.1.0
Windows 2016 Standard Edition - Hyper-V
SMB shares are exported from the Windows Server. These are NTFS- and ReFS-backed shares in a Storage Spaces mirrored environment.
localhost ~ # mount.cifs -V
localhost ~ # mount | grep cifs
Normal access to CIFS shares for reading/writing.
Running docker-compose up to start containers results in immediate kernel panic. Writing a large file causes a kernel panic as well.

Thanks for the report. It seems this was introduced by coreos/linux@748144f in 4.14.55. A revert of that commit is already queued for 4.14.59.
1828.1.0 is on the beta channel, which also ships the 4.14 kernel. The alpha channel ships 4.17 and should not have this problem. Could you test the latest alpha and confirm?
